Wind Direction Reading

As I stated in the previous post, the readings of this sensor take a lot of work to setup. You have to get a reading at each direction and then split the difference between them to get a high and low. Somewhere I have an excel file that I use to do all the calculations and print out the code. I’ll load it here if/when I find it.

To use this, you will need to place an include in your python program:

from wind_dir import wind_dir

Then when you want to get the value, you call the function with your ADC reading:

wind_direction = wind_dir(wind_dir_read)

The annoying part of this is setting up this file. All it does is take your reading and see where it falls within the table of max & min values established through testing:
